The paper presents the results of the geophysical multi-method survey that was carried out in order to map the contamination migration pathways in the vicinity of waste disposal ponds of one of the biggest Polish chemical plant, located in central Poland. Three geophysical methods were adopted for this survey: EM profiling, ERT resistivity surveys and direct push resistivity logging. While EM profiling was chosen for surface area mapping, the application of ERT method was aimed at vertical characterization of the contamination distribution. Finally, the direct push resistivity logging was performed at two locations, with the aim of verifying the ERT interpretation. As a result, several extremely high conductivity/low resistivity anomalies has been identified, that can be attributed to the migration pathways from waste ponds. The survey results for each method applied here are shown, and emphasis is placed on comparison between the results obtained with each individual method. Differences in the resistivity/conductivity image of the area can be explained as arisen from different spatial characteristics of each method applied.
